As my Bronco gets closer to being ready, I'm trying to keep in mind getting our tow rig ready as well. It's a 2wd 2011 Suburban LT2, 5.3 (dreaded DOD) 6 speed, 168k miles. I need to go through and do the brakes on it and get a trailer brake controller to go with the trailer I'm using. Not 100% sure on the entire specs of it, but it's dual axle, electric brakes, breakaway, etc. My step-father got it with an old Ford Tractor he bought. Should be more than enough to tow the Bronco to Uwharrie until we can shell out for our own. So beyond, the obvious brakes, fluids, brake controller. What things should I be looking into on this rig? I've heard the 6 speed can have issues so I should start saving to have an upgrade built when it goes. We've had the truck for about 40k miles and just kept up with simple maintenance, don't know the service history before we got it. I'm assuming I can't go wrong with a trans filter/fluid service (Not sure a full flush would be worth the time or cause more harm than good). This will be the first time I've done any towing with my own vehicle, I've always used others rigs before that were already setup/ maintained for towing so just trying to not breakdown on the first trip out because of something preventable. DOD seems to be fouling plugs from time to time, we had a miss after we had it about a year and the DOD cylinders had oil on the spark plugs, replaced them and haven't had any issues since. Maybe if the trans goes, it will be time to replace the cam and lifters, but that is a discussion for another day. I know it sounds like some stupid questions, just trying to be prepared and not be a burden on any group i'm riding out with. I appreciate any advice.
